Can't agree with you. Airdrops are beneficial both for the noobs who get the coins for free, and for those who invest in the currency. The noobs get free money, while the serious investors benefit from the price rise, which will naturally occur when the user-base expands as a result of the airdrop. And not all of those who receive airdropped coins dump them right-away. Most of them keep at least 20% to 50% of the coins for long-term.
